Try directing your attention towards the Trade Center board [link] (http://www.pokecommunity.com/forumdisplay.php?f=161) specifically, but make sure you're aware of the board-specific rules there first, as well as the Community Rules (http://www.pokecommunity.com/showthread.php?p=6446812). Your stay here will be a muuuuuch more pleasant experience if you take a quick glance at those two.
